Abstract
Naturally occurring akaganeite (1) was analyzed and compared to synthetic beta-FeOOH. The I occurred with magnetite, goethite, and lepidocrocite as oxidation products in ancient iron implements. Tests conducted included x-ray analysis, Moessbauer spectral analysis, electronprobe x-ray microanalysis and thermal analysis. The I contained 3.5 wt.% Cl. Some Cl<sub>-</sub> and F<sub>-</sub> is necessary for formation of the beta-FeOOH crystal structure. The Cl was derived from salt buried with the iron implements. -- AATA
